Is gardening a guerilla?Is the concrete a real jungle? These Flower Grenades are originally designed for adding flowers to urban areas that need some beautification. But I think it’s fun no matter where you live. Tossing a flower grenade is fun, and watch seeds growing is simply beautiful. Each grenade is filled with soil, poppy, rye grass and buttercup seeds and the clay shell is totally biodegradable. Each box contains 3x air dried clay hand grenades, each Flower Grenade contains soil, poppy, rye grass and buttercup seeds. Breed flowers, not war!
